How to setup iPod Shuffle (or Aux) on a 987

[wt888usa]

I have an 06 987, with a Bose sound system. I want to basically play the music on my iPod on the system, but don't need any of the fancy ipod integration with track names or anything, just basically want an auxiliary port to plug in my ipod shuffle (or other devices, like a PSP). what solutions do you guys suggest? the dension gateway 500 seems like overkill for my needs...
